KGUN-TV reported that the medical examiner there had brought in an anthropologist in an attempt to determine the man's age, and they were also trying to find what tool was used to sever the appendages.

The man was likely about 5-feet, 8 inches tall and weighed about 180 to 200 pounds, the television station reported.

In Los Angeles, detectives Wednesday afternoon found a pair of feet buried in a shallow grave. Two hands were also found nearby.

They began combing through Bronson Canyon Park, near the Hollywood sign, on Tuesday afternoon after dog walkers discovered the head when their dogs were playing with a plastic bag and they went to inspect it.

Although the law enforcement agencies have been in contact, Pima County's chief medical examiner, Dr. Gregory L. Hess, told The Times that "preliminarily the cases appear unrelated."
